Abstract

A process for preparing self-extinguishing formed thermoplastic bodies based on polycaprolactam, which consists in polymerizing, by anionic way, in suitable molds s-caprolactam, by previously incorporating into said s-caprolactam a flame-retardant and optionally at least a known coadjuvant substance, said flame-retardant being composed of red phosphorus powder micro-encapsulated in a synthetic resin, preferably in a melamine resin.
